This document is a detailed electrical wiring diagram for a clock system on a naval vessel, specifically for the T-AGS 51/52 Coastal Hydrographic Survey Ships. The diagram shows the interconnection of a master clock unit located in the chart room and multiple slave clocks distributed across different ship locations, including the radio room, pilot house, chief engineer's senior quarters, captain's senior quarters, chief scientist's senior quarters, crew mess, officer mess, galley, and survey control center.

The technical drawing includes specifics such as cable types (LS DSG-4 and LS250-10, both low smoke), junction box configurations (C-CE1 and C-CE2), terminal connections, and color-coded wiring (with abbreviations like BR for brown, B for black, R for red). The document is part of a contract with Halter Marine Inc. for the Department of the Navy's Naval Sea Systems Command, dated August 24, 1990, with a drawing number of 663472727 and revision A. The diagram provides a comprehensive view of the clock system's electrical wiring design, including jumper configurations and shield grounding instructions.
